THOMAS A. DE VILBISS, OF

TOLEDO, OHIO, ASSIGNOR TO THE DE VILIBISS MANUFAC- TUBING 00., OF TOLEDO, OHIO, A CORPORATION OF OHIO.

ATOMIZEB.

Application filed December 6, 1915.

To all whom it may concern Be it known that I, THoMAs A. Dr. VIL- BISS, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Atomizer; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to atomizing instruments of the type employed for applying a,medicated liquid in spray or, finely atomized form to the nose and throat.

The object of my invention is the provision of improved means for attaching a nasal tip to the discharge nozzle of an atomizer, which tip is adapted to have sliding spring engagement with the nozzle carrying parts to ieldingly retain the tip in operative relation to the nozzle and to facilitate an easy and quick placing on or removing of the tip from the nozzle, thus enhancing the practicability and commercial value of instruments of this character.

The invention is fully described 'in the following specification, and while, in its broader aspect, it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in which,--

Figures 1 and 2 are top plan and side views of an atomizer. embodying the invention, and Fig. 3 is an enilarged view of a portion of the air and liqu d discharge tubes of an atomizer and associated nozzle with a nasal tip mounted thereon and in section.

Referring to the drawings, 1, 1 designate the air and liquid discharge tubes of an atomizer, which tubes are disposed side by side and have their outer end portions sprung apart and terminating in inwardly turned portions 2, which form trunnions for-fitting into axially alined openings provided in the opposite sides of a nozzle 3 adjacent to its rear end, asindicated in Fig. 3 and as well understood in the art. It will be understood that the bores of the two tubes 1, 1 open into a common discharge orifice in theinozzle 3.

The atomizer tubes 1, 1 are made of spring Specification of Letters Patent.

metal and have their outer sides tapering slightly outward for a short distance rearwardly from their forward ends so that the distance between the outer sides of the tubes 1s the greatest a short distance back from the nozzle, is preferable, but not necessary, to tie the tubes together in closely disposed relation intermediate their ends, as by a band 4, so that the outer sides of the tubes taper in opposite directions to the point of the nozzle.

The nasal tip 5 is of elongated shell form, bein'g preferably formed from sheet metal, and has its forward end closed except for a central opening 6 provided therein and of suitable size for the discharge end of thenozzle 3 to project through. The tip 5 is preferably tapered or gradually enlarged in diameter for a distance rearward from its forward end and then slightly contracted in gradually tapering form to slightly restrict the rear open end of the tip. The tip 5 is of suitable length to cause its rear restricted end to extend slightly beyond the point of maximum width of the two tubes 1, 1 when the tip is placed over the nozzle and the outer ends of the tubes, with the nozzle projecting through the tip opening 6. The tip is circular in diameter of the rear end opening thereof is slightly less in length than the distance betweenthe more remotely spaced outer side portions of the tubes, thereby causing the tip when forced rearward into operative position over the tubes to effect a slight inward springing of the tubes, the normal outwardly sprungposition of which is indicated by the dotted lines 7 in Fig. 3.

It is evident. that the cooperative spring engagement of thetubes 1 and rear end of the tip 5 in the manner described quite firmly holds the and at the same time facilitates an easy and quick placing on or removal of the same from the tubes. It is also evident that the projecting of the nozzle 3 through the restricted o ening 6 in the forward end of the ti effects a centering of the forward end 0 the tip with respect to the nozzle and serves to prevent any transverse twisting or displacing movements of the tip with respect to the nozzle and tubes.

I wish it understood that my invention is not limited to any specific construction,

as best indicated in Fig. 3. It

cross-section and the tip in position on the tubes arrangement or form of theparts, as it is capable of different modifications without departing from the spirit of the claims.

Having thus described my invention, what I claim as newand desire to secure by Let-,

ters Patent, is Y 1. In an atomizer, a nozzle air and liquid discharge tubes carrying said nozzle and projecting rearwardly therefrom in transversely spaced. relation, said tubes having the distance'between their outer sides broadened with respect tot-heir forward ends at a point which is distant from said ends, and a nasal tip for removably receiving the nozzle and forward end portions of said tubes,

said tip being of a length for its rear end to extend beyond the broadened portion of said tubes and having its rear .end opening of a size less than the distance between the broadened outer side portions-of the tubes placed in operative engage and a nasal tip for fitting over said nozzle and the forward end portions of said tubes and having its forward end provided with a restricted opening for receiving and cooperating with the nozzle to'center the tip with respect thereto and having its rear end adapted to coact with the bulged portion of said tubes to yieldingly retain the tip in position thereon.

3. In an atomizer, a nozzle, air and liquid tubes projecting rearwardly in spaced rela tion from opposite sides of said nozzle and having their outer sides tapered outward for a distance from their forward ends, and a nasal tip for fitting over said nozzle and the outwardly tapered end portion of said tubes, said tip having a restricted opening in its forward end for receiving and coacting with the nozzle to center the tip there-- with and having its rear .end slightly contracted. and coacting with said tubes ata distance from their forward ends, to effect an inward springing of the tubes when the tip is placed thereon. y

In testimony whereof I have hereunto signed my name to this specification.
